I have an Iron Horse Warrior 3.0, this bike was kind of handed down. I am having trouble figuring out which one I would like to use as my main bike. The cost for maintenance for the GT just kind of intimidates me because I feel that it would be a lot higher.

It should intimidate you, as parts are hard to come by, if at all, and the old components on it will cost a lot to replace with newer stuff. Once done with "modern" stuff, the problems such as mismatched geometry to a newer fork remain, along with such things as the cost of replacing all that stuff with modern stuff is just about the cost of buying a complete, above-entry-level HT.

I must agree with JC on the cost part. Keeping a vintage rig can be a costly decision and may not do you too good unless it is your passion. Granted, older GT are still somewhat modern capable (1 1/8 head tube, bb & cranksets can be swapped out with modern ones no problem, there are some 80mm forks available, etc), but unless you ride it like a beater, it will cost you some. Just by looking at it, you’ll probably need a new fork from the get-go. Those suspensions were innovative things back then, but it won’t stack up among current design – you will notice this immediately, especially if you already have a modern design.

In my opinion, unless you are a) passionate about old bikes, b) willing to spend some $ to restore it, and c) be satisfied with what it is, then you may be in for a disappointment. [SIZE="1"]I'd sell it if I were you.[/SIZE]
